Abstract
Provided is a laser welded body which can be manufactured without undergoing complicated steps and maintain the characteristics of a resin contained in a resin member, which exhibits high welding strength even when scanned with a laser beam at a high speed, and which can be manufactured at high production efficiency. The laser welded bodycomprises a first resin memberwhich is a laser-irradiated subject which contains a thermoplastic resin and nigrosine sulfate and has an absorbance aof 0.09 to 0.9; and a second resin memberwhich contains a thermoplastic resin as the same kind as or different kind from the thermoplastic resin and a laser beam absorbent, and has an absorbance aof 3.0 to 15, wherein the first resin memberand the second resin memberare laser-welded at a part at which the both resin members are overlapped and/or butted.
